E-mail: Microsoft’s Johnson on his departure

Here’s the e-mail message sent by Kevin Johnson, Microsoft’s departing Platforms and Services president, to employees of the division. Although he doesn’t identify the company where he’ll be chief executive, the Wall Street Journal reports it is Juniper Networks.

Microsoft is a wonderful company, creating software experiences which continue to change the world. I have been fortunate to have experienced 16 amazing years building Microsoft’s business, serving customers and partners, learning from great leaders in the company, and working with phenomenally talented people.

I wanted to let you know that I will be leaving Microsoft and will become CEO of a leading technology company in September.

Transitioning from Microsoft is an emotional decision, as I have enjoyed working at this company for so many years. I have learned a great deal from Steve, Bill, and many other leaders at Microsoft. Microsoft is a big part of my life and I will always cherish the fond memories of my years here. I am proud of what we have built together, and I am so optimistic about Microsoft’s future.

Being a CEO will be a new experience for me and it is the right time for me to pursue this change. I will be here partnering with Steve and the PSD leadership team to ensure a thoughtful and well managed transition. I am absolutely confident in the PSD leadership team and know they will continue to drive hard on the Windows and Online Services priorities as we kick off FY09.

Thanks again to all of you, and I wish you continued success in the future.

Update, 9 a.m.: Juniper is now confirming Johnson’s appointment as its next chief executive. See the news release here.
